DETAILED DESCRIPTION

Although various embodiments of the invention may have been motivated by various deficiencies with the prior art, which may be discussed or alluded to in one or more places in the specification, the embodiments of the invention do not necessarily address any of these deficiencies. In other words, different embodiments of the invention may address different deficiencies that may be discussed in the specification. Some embodiments may only partially address some deficiencies or just one deficiency that may be discussed in the specification, and some embodiments may not address any of these deficiencies.

In general, at the beginning of the discussion of each of FIGS. 1A-6 is a brief description of each element, which may have no more than the name of each of the elements in the one of FIGS. 1A-6 that is being discussed. After the brief description of each element, each element is further discussed in numerical order. In general, each of FIGS. 1A-8 is discussed in numerical order and the elements within FIGS. 1A-8 are also usually discussed in numerical order to facilitate easily locating the discussion of a particular element. Nonetheless, there is no one location where all of the information of any element of FIGS. 1A-8 is necessarily located. Unique information about any particular element or any other aspect of any of FIGS. 1A-8 may be found in, or implied by, any part of the specification.

FIG. 1A shows a side view a craft 100 to which an embodiment of pump system 101 (according to an embodiment of the invention) has been attached. Shown in FIG. 1A as either part of craft 100 or pump system 101 are grab loop handle 102, bulkhead adjustment rail 106, fastener 108, intake hose 110, cockpit 112, seat 114, first bulkhead 118, second bulkhead 120, hose clamps 122, exhaust hose 126, pump chamber 200, intake port 300, and through hull exhaust port 400. In other embodiments, craft 100 and/or pump system 101 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

Although in FIG. 1A craft 100 is depicted as a kayak, craft 100 may be any of a number of different types of crafts for which a paddle or oars are used, such as a kayak, canoe, or row boat. Craft 100 may also be any other type of craft in which the user performs repetitive motions (e.g., peddling) as part of operating the craft in which part of the repetitive motion (e.g., pushing down on a peddle) may be used to activate a pump chamber. For example, craft 100 may be any craft within which the user tends to perform a repetitive motion (e.g., a repetitive motion craft). Consequently, the user of craft 100 may be a paddler or a rower or other type of operator of a craft depending on the specific embodiment of craft 100. Additionally, craft 100 is not necessarily a water craft, but may be (for example) another type of craft having an enclosure within which water may collect, such as an enclosed peddle powered go cart being used in the rain. Finally, craft 100 may be intended to operate on a tank containing a fluid other than water (e.g., sludge).

Grab loop 102 may be used for lifting or carrying craft 100. Bulkhead adjustment rail 106 may be used for adjusting and/or fixing the bulkhead in various positions for different sized users. Fastener 108 fastens intake hose 110 to bulkhead adjustment rail 106. Intake hose 110 has one end at or near the bottom of craft 100 and the other end connected to a pump chamber. Fluids that collect on the floor of craft 100 may be brought to the pump chamber via intake hose 100. In other embodiments, intake hose 100 may be secured to other items, such as the walls of craft 100 in addition to or instead of being fastened to bulk head adjustment rail 106. Securing intake adjustment hose in place may decrease the likelihood of damaging or disconnecting intake adjustment hose 110 while paddling. Alternatively, intake hose 110 may be left partially dangling, fully dangling, or routed through foam blocking inside the craft. Cockpit 112 may be used to sit in by the user while paddling. Seat 114 may be located within cockpit 112. The user may sit in seat 114 while paddling. First bulkhead 118 may be made from a flexible foam material, such as a polystyrene plastic (often sold as Styrofoam®), and may be used for the user to rest his or her feet. If craft 100 is a kayak, canoe, or rowboat having a bulkhead, the user's feet may press against first bulkhead 118 while paddling or performing another repetitive motion associated with using craft 100. First bulkhead 118 may have the shape of a rectangular sheet or a rectangular block, and may have a recess carved or otherwise formed on one or more side for receiving the pump chamber. Second bulkhead 120 (which may be made from a rigid plastic or other rigid material) may provide a stable platform for supporting first bulkhead 118 and the user's feet while the user's feet presses against first bulkhead 118 while paddling. First bulkhead 118 and second bulkhead 120 form a mount for the pump chamber. Hose clamps 122 fasten hoses to various ports. Hose clamps 122 fasten intake hose 110 to the intake port and to a port on the pump chamber, and fasten the exhaust hose to the pump chamber and to an exhaust port. Exhaust hose 126 is used for bring fluids from a pump chamber to a location exterior to craft 100.

Pump chamber 200 may include a chamber that is capable of holding and pumping a fluid. Pump chamber 200 may include a resilient flexible material, and may be characterized as a bladder. Pump chamber 200 may be mounted within a recess of first bulkhead 118. In an embodiment, intake port 300 of the system is located at or near the lowest point of the craft 100 (possibly under seat 114). Intake port 300 is connected to an intake hose 110, which travels to the front of craft 100. Intake hose 110 is secured by fasteners 108 to bulkhead adjustment rail 106. Securing intake hose 110 helps prevent intake hose 110 from moving around and being disconnected. Intake hose 110 connects intake port 300 to pump chamber 200. Exhaust hose 126 connects from the pump chamber 200 to through hull exhaust port 400. Although in FIG. 1A exhaust port 400 is located just in front of cockpit 112, where exhaust port 400 is easy to reach, in other embodiments exhaust port 400 may be located further from cockpit 112 and/or angled away from cockpit 112.

Pump chamber 200 is discussed further in conjunction with FIG. 2. Intake port 300 is discussed further in conjunction with FIG. 3. Exhaust port 400 is discussed further in conjunction with FIG. 4.

FIG. 1B shows a top view of craft 100 with pump system 101. Shown in FIG. 1B as either part of craft 100 or pump system 101 are grab loop handle 102, bulkhead adjustment rail 106, fastener 108, intake hose 110, cockpit 112, seat 114, first bulkhead 118, second bulkhead 120, hose clamps 122, exhaust hose 126, pump chamber 200, intake port 300, and through hull exhaust port 400. In other embodiments, craft 100 and/or pump system 101 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

Pump system 101, grab loop handle 102, bulkhead adjustment rail 106, fastener 108, intake hose 110, cockpit 112, seat 114, first bulkhead 118, second bulkhead 120, hose clamps 122, exhaust hose 126, pump chamber 200, intake port 300, and through hull exhaust port 400 were discussed in conjunction with FIG. 1A (additionally, as mentioned above, pump chamber 200 will be discussed further in conjunction with FIG. 2, intake port 300 will be discussed further in conjunction with FIG. 3, and exhaust port 400 will be discussed further in conjunction with FIG. 4).

In the embodiment of FIG. 1B, pump system 101 is installed in the right side of craft 100. There are many other embodiments of this invention. In an embodiment, multiple pump chambers and multiple intake ports can also be used. Also, pump chamber 200 can be in various locations that would still receive pressure from a user's body during the operation of the craft. In one embodiment, multiple pump chambers and multiple intake ports can be used to provide more pumping capability. For example, two pump systems may be installed, such that each side of craft 100 has one pump. Specifically, in one alternative embodiment, pump system 101 is installed in the left side of craft 100 in addition to or instead of being installed on the right side. As another example, in addition to or instead of pump chamber 200, a pump chamber can be installed in a variety of other places, such as the seat back-band, the seat pad, under the seat, and/or in the thigh braces of the craft and inside or mounted too a padded foot bag (for small kayaks). Pump chamber 200 may be placed in any location that causes energy being expended on paddling, steering the craft, or another repetitive motion to activate pump chamber 200 (e.g., by depressing pump chamber 200). From the description above, it can be seen that in the embodiment in which craft 100 is a paddle craft, when paddling, a person applies pressure to the bulkhead of the craft to propel it forward and to steer it. Pump system 101 may use that pressure to remove water. Since pumping does not require any separate action by the user, a user may not even realize that they are operating pump system 101. Embodiments of pump system 101 may be constructed such that pump system 101 is very lightweight, and may only add approximately 1 pound to the overall weight of the craft. Using pump chamber 200, the user can vary the amount of water removal by varying the degree to which pump chamber 200 is depressed, which may be accomplished by changing the user's foot position so that the user's foot depresses a small portion of pump chamber 200. Compressing the entire chamber of pump chamber 200 results in maximum displacement, whereas compressing the edge (normal foot position) of pump chamber 200 results in minimum displacement.

Thus, pump system 101 may effectively and efficiently remove fluids from craft 100 without requiring the operator to perform a separate action. Simply by paddling or performing another repetitive action associated with using craft 100, the user will remove fluid if any is present in craft 100. Furthermore, if craft 100 is a water craft, pump system 101 may provides a method to return to safety should a crack develop in the hull of craft 100. Also, in the case in which pump system is a water craft, pump system 101 may help keep the user warm and/or safe by removing cold water or another fluid from inside craft 101. Similarly, craft 100 may be kept lighter and more maneuverable by using pump system 101 to remove water or another fluid from craft 100. Also, in the case of craft 100 having a spray skirt (or spray deck), pump system 101 may be used to remove water or another fluid without having to remove the spray skirt, and thereby avoiding exposing the user to the possibility of an influx of more water or another fluid. The capability of removing water or another fluid from craft 100 without removing the spray skirt is useful when the body of water or other fluid does not have are a calm spot or a spot with eddies within which the spray deck may be safely removed.

FIG. 1C shows a top view of a craft 100 to which is attached an embodiment of a two chamber pump system 151. Shown in FIG. 1C as either part of craft 100 or pump system 151 are grab loop handles 102, barbed tee 104, bulkhead adjustment rails 106, cockpit 112, seat 114, second bulkhead 120 (first bulkhead 118 is not present in this embodiment), exhaust hose 126, intake hose 110, drain plug opening 162, pump chambers 200 a and 200 b, intake port 300, and through hull exhaust port 420. In other embodiments, craft 100 and/or pump system 151 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

Grab loop handle 102, bulkhead adjustment rail 106, cockpit 112, seat 114, second bulkhead 120, and intake port 300 were discussed as part of FIG. 1B. Pump chambers 200 a and 200 b of FIG. 1C may be the same as pump chamber 200 discussed in conjunction with FIGs. 1A and 1B. FIG. 1C simply illustrates how two barbed tees 104 may parallel two pump chambers 200 a and 200 b.

FIG. 2 shows an embodiment of the pump chamber 200. Pump chamber 200 may include an intake connection 202, a exhaust connection 204, mounting tabs 206, check valve housing 208, exhaust check valve 210, and intake check valve 212. In other embodiments, pump chamber 200 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

Although in the example of FIG. 2, pump chamber 200 has an oval shape, pump chamber 200 can have various shapes such as triangular, trapezoidal, etc. In an embodiment, the positions of the intake check valve 212 and exhaust check valve 210 may be swapped to allow for a simple parallel connection of the pump chambers as shown in system 151. Also, in an embodiment, intake connection 202 and exhaust connection 204 may be barbed nipples that are capable of swiveling 360 degrees. In other embodiments other forms of connections may be used, which may or may not be barbed, and may or may not swivel 360 degrees. For example, intake connection 202 and/or exhaust connection 204 may have threaded ends to which hoses may be screwed or may have ends that do not have any threads and are not barbed. Similarly, intake connection 202 and/or exhaust connection 204 may not swivel at all or may swivel an amount less than 360 degrees. Using a barbed shape for intake connection 202 and exhaust connection 204 may aid in securing in place hoses that are attached thereto. Constructing intake connection 202 and exhaust connection 204 so that they swivel may also facilitate connecting hoses to intake connection 202 and exhaust connection 204 from any direction. Any of a variety of pump chambers may be used instead of pump chamber 200. For example, the intake and exhaust may be simple flexible or rigid tubes instead of intake connection 202 and exhaust connection 204. In an embodiment, instead of or in addition to mounting tabs 206, pump chamber 200 may be held in place with clamps, straps, brackets, epoxy, and/or braces. Check valve housing 208 protects check valves located within the check valve housing. Exhaust check valve 210 and intake check valve 212 mounted inside the check valve housing 208. Exhaust check valve 210 allows fluids out of, but not into, pump chamber 200. Intake check valve 212 allows fluids into, but not out of, pump chamber 200. In an alternative embodiment, check valve housing 208 may not be included, and/or exhaust check valve 210 and/or intake check valve 212 may be mounted elsewhere.

FIGS. 3A and B show an example of intake port 300. Specifically, FIG. 3A shows the side of one embodiment of the intake port 300, and FIG. 3B shows the top of one embodiment of intake port 300. Intake port 300 may include of a connection 304, intake orifice 302, recessed grooves 306, sand screen 308, and threaded hole 312. In other embodiments, intake port 300 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

In one embodiment, intake port 300 may be fused or glued to the hull of craft 100. Other methods of mounting may include a bracket or screw. Intake orifice 302 may help collect fluid, and may provide a hollow passage that allows fluid to be drawn from the bottom of craft 100 to connection 304. Connection 304 provides a rigid connection point for the intake hose to terminate. In an embodiment, connection 304 may be a barbed nipple. In other embodiments other forms of connections may be used, which may or may not be barbed. For example, connection 304 may have threaded ends to which hoses may be screwed or may have ends that do not have any threads and are not barbed. Using a barbed nipple for connection 304 may aid in securing in place hoses that are attached thereto. Recessed grooves 306 may allow and/or direct fluid movement towards intake orifice 302 through sand screen 308, and may help collect the fluid that enters intake orifice 302. Fluid collected via recessed grooves 306 may be drawn through a hollow passage way including intake orifice 302 to connection 304.

In another embodiment, intake port 300 may be the end of a tube that is secured to a location at or near the bottom of craft 100. Although in the embodiment of FIG. 3, intake orifice 302 is above and facing hull of craft 100. In another embodiment, two holes are placed at or near the bottom of craft 100, one hole is above intake port 300, and intake orifice is located below hull and outside of craft 100 facing up for collecting fluids. Another hole allows a tube to connect to orifice 302 to enter craft 100 so that the fluid collected by intake port 300 may be pumped by pump chamber 200, or 200 a and 200 b upward and out of exhaust port 400 or 420.

FIGS. 4A-C show an example of through hull exhaust port 400. Specifically, FIG. 4A shows a side view of one embodiment of through hull exhaust port 400. FIG. 4B shows a top view of one embodiment of through hull exhaust port 400 in a closed position. FIG. 4C shows a top view of one embodiment of through hull exhaust port 400 in an open position. Through hull exhaust port 400 may include on/off selector cap 402, sealing gasket 404, locking nut 406, threaded shaft 408, and barbed hose connector 410. In other embodiments, through hull exhaust port 400 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

On/off selector cap 402 allows the user to turn the system on and off by rotating selector cap 402 by a rotation of 90 degrees. Conical shaped sealing gasket 404 allows exhaust port 400 to fit in various sized openings (for the drain plug opening alternate detailed in FIG. 5) and creates a seal preventing water from entering. Locking nut 406, which tightens on the threaded shaft 408, holds the exhaust port 400 in place and provides pressure to seal the opening. In an alternative embodiment, exhaust port 400 may be glued (with water proof glue) and/or clamped and sealed in place in addition to or instead of using lock nut 406. Exhaust hose 126 connects to the barbed hose connector 410 and is secured with hose clamps 122. Placing on/off selector cap 402 in the off position may cause pump chamber 200 to become firm. The on position can be obtained by a quick rotation of the on/off selector cap 402, which may be located at a location that is expected to be within reach of the user, so that the user does not need to exit craft 100 to change the position of on/off selector cap 402.

In another embodiment, hull exhaust port 400 may be any of a variety of other types of ports. For example, hull exhaust port 400 may be nothing more than the end of a tube that is secured to the outside of the hull of craft 100, such that fluid pumped out of craft 100 is not expected to ordinarily re-enter craft 100. In another embodiment, exhaust port 400 may be a one-way valve that is expected to allow fluids to exit, but is also expected to not allow a significant amount of fluid to enter. In another embodiment, exhaust port 400 may have a cap and/or a lid that flips open in addition to or instead of a rotating cap.

FIG. 4D shows a side view of through hull exhaust port 420. Through hull exhaust port 420 may include sealing gasket 422, barbed hose connector 424, and handle 428.

Through hull exhaust 420 is a hollow threaded plug that may screw into the existing drain plug opening of craft 100 or other opening in craft 100. The embodiment of FIG. 4D also includes sealing gasket 422, barbed hose connector 424, and handle 428. Sealing gasket 422 creates a water tight seal between the hull of craft 100 and through hull exhaust 420. Barbed hose connector 424 may connect to exhaust hose 126. Handle 428 may be used to grasp the exhaust port 420 and screw it into place.

FIG. 4E shows a top view of through hull exhaust 420 having hollow center 426. Water from exhaust hose 126 exits through hull exhaust 420 via hollow center 426. In other embodiments, through hull exhaust 420 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

FIG. 5 shows an additional embodiment, which is system 500. FIG. 5 shows craft 100, hose clamp 122, exhaust hose 126, drain plug opening 162, and through hull exhaust port 400 or 420, which were described in conjunction with FIG. 1 and FIGS. 4A-E, above. In other embodiments, system 500 may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

System 500 may be installed without adding another hole to the hull of craft 100, and may therefore be used as an after market add-on. System 500 works almost identically to the embodiments of FIGS. 1A-4E. System 500 does not require the user to drill a hole in his/her craft, because the through hull exhaust port 400 or 420 is mounted in the existing drain plug opening of craft 100.

FIG. 6A-B show another embodiment of pump system 101. FIG. 6A-B show craft 100, grab loop handle 102, fastener 108, intake hose 110, cockpit 112, seat 114, first bulkhead 118, second bulkhead 120, hose clamps 122, exhaust hose 126, pump chamber 200, intake port 300, through hull exhaust port 400, foot peg 618, and foot peg adjustment rail 620. In other embodiments, the system of FIG. 6A-B may not have all of the parts listed and/or may have other parts instead of or in addition to those listed.

Craft 100, grab loop handle 102, bulkhead adjustment rail 106, fastener 108, intake hose 110, cockpit 112, seat 114, hose clamps 122, exhaust hose 126, pump chamber 200, intake port 300, and through hull exhaust port 400 were discussed in conjunction with FIGs. 1A-4D, above.

In FIG. 6, foot peg 618 is used instead of an adjustable bulkhead. The pump chamber 200 can be mounted on or next to the foot peg 618 in such a way that allows the user's foot to compress the chamber.

FIG. 7 shows a flowchart of an example of a method of installing pump system 101 or 151 in craft 100. A manufacturer of craft 100 or end user may install pump system 101 or 151 in a similar manner (as detailed in FIG. 7). In step 700, the pump chamber 200 is, or 200 a and 200 b are, screwed to the second bulkhead 120. For crafts with a first bulkhead 118, in step 701 an oval is cut into first bulkhead 118 to receive pump chamber 200 (or 200 a & 200 b). In step 702, first bulkhead 118 (if present) is glued to second rigid bulkhead 120. In step 704, the user selects the existing drain plug opening or drills an additional hole on the bow of craft 100. Additionally, through hull exhaust port 400 or 420 may be installed by tightening locking nut 406 or twisting handle 428, respectively. In step 706, the intake port 300 is glued, fused, screwed, or otherwise secured in place with respect to the hull of craft 100 at or near the lowest point of craft 100. In step 708, exhaust hose 126 is connected from pump chamber 200 via exhaust connection 204 (or from pump chambers 200 a and 200 b with barbed tee 104) to through hull exhaust port 400 or 420 (and, in the case of the embodiment of FIG. 1B, is secured with hose clamps 122 and fasteners 108). In step 710, the intake hose 110 is connected from the intake port 300 to the intake connection 202 on the pump chamber 200 (or to barbed tee 104 and then to 202 a and 202 b).

In an embodiment, each of the steps of method of FIG. 7 is a distinct step. In another embodiment, although depicted as distinct steps in FIG. 7, steps 700-710 may not be distinct steps. In other embodiments, the method of FIG. 7 may not have all of the above steps and/or may have other steps in addition to or instead of those listed above. For example, in an alternative embodiment, intake port is allowed to rest on the floor of craft 100, without being attached to craft 100 and/or intake port 300 is just the end of intake hose 110, in which case steps 706 and/or 710 are skipped. The steps of the method of FIG. 7 may be performed in another order. Subsets of the steps listed above as part of the method of FIG. 7 may be used to form their own method. The method of FIG. 7 may be stored on a machine readable media as a set of machine instructions for controlling equipment in a factory that attaches pump system 101 to craft 100.

FIG. 8 shows a flow chart of an example of a method of operating pump system 101 or 151 after the pump system has been installed in a paddle craft or row boat. When operating craft 100, the user exerts forces on said craft to propel and steer it. This energy is utilized to operate a pump system for removing nuisance water from the craft. As detailed in FIG. 8, step 800 starts the process when a user takes a forward stroke and compresses the pump chamber 200 or 200 a and 200 b with his/her foot. In step 802, when the foot pressure is released, the elastic nature of the chamber 200 or 200 a and 200 b causes it to expand. Due to check valve 210 inside the pump chamber, the water is drawn into the chamber from the intake port 300. In step 804, when the next paddle stroke is taken, the pump chambers 200 or 200 a and 200 b are again compressed. In step 806, the closing of the pump chamber check valve 212 forces the water towards the through-hull exhaust port through the exhaust hose 126 and is jettisoned from craft 100.

In an embodiment, each of the steps of the method of FIG. 8 is a distinct step. In another embodiment, although depicted as distinct steps in FIG. 8, step 800-806 may not be distinct steps. In other embodiments, the method of FIG. 8 may not have all of the above steps and/or may have other steps in addition to or instead of those listed above. The steps of the method of FIG. 8 may be performed in another order. Subsets of the steps listed above as part of the method of FIG. 8 may be used to form their own method.

A kit may be constructed that includes the components of the pump system of any of the embodiments of FIGS. 1A-6 and a set of instructions describing a method of assembling the kit, such as one of the embodiments the method of FIG. 7, and/or a method of using the kit after the kit is assembled, such as one of the embodiments of the method of FIG. 8. The set of instructions may be stored on any of a number of storage media, such as paper or a machine readable media (e.g., a computer readable media), such as a Compact Disc (CD), in a form that a human may read and understand.
